Toronto, OntarioAges 18 years+ - NCT04865315Recruiting
Donate tumor samples to build organoid tissue from glioma
This study collects tumor tissue during brain surgery to create lab-grown “organoids” (mini models of the tumor). It aims to build a tissue bank that researchers can use to better study gliomas and develop treatments.
Maastricht, LimburgAges 18 years+ - NCT04866654RecruitingPhase 2
Test chemotherapy without radiation for early Hodgkin lymphoma
This Phase 2 study tests whether you can treat early-stage Hodgkin lymphoma with chemotherapy while avoiding radiation. It may help reduce radiation-related side effects if the treatment controls the cancer effectively.
Pavia, P.le Golgi 19Ages 18–60 - NCT04888338Recruiting
Studying outcomes after CAR-T, radiation, or bispecific therapy
This study looks at how people with blood cancers do after they receive CAR-T therapy, radiation therapy, and/or bispecific therapy. It may help doctors understand which treatment combinations work best and what side effects to expect.
Houston, TexasAges 18 years+ - NCT04892303RecruitingPhase 1
Planning treatment using radiation plus radioactive iodine for thyroid cancer
This Phase 1 study tests how doctors plan a combination of two radiation approaches—external beam radiation and radioactive iodine—for thyroid cancer that is not fully responding to standard treatment. It may help people who still have iodine-avid tumor spots, but whose iodine uptake looks too low to work well with radioactive iodine alone.
Baltimore, MarylandAges 18–85 - NCT04923542RecruitingPhase 1/Phase 2
Targeted drug plus focused brain radiation for breast cancer
This study tests whether abemaciclib (a targeted pill) given with focused radiation to brain tumors can control hormone receptor–positive, HER2-negative breast cancer in the brain. It’s designed to see if the combination helps shrink or slow the growth of brain metastases while keeping side effects manageable.
Tampa, FloridaAges 18 years+ - NCT04933435Recruiting
Image-guided radiation plus liver procedures for non-surgical liver cancer
This trial studies a combination approach—special, image-guided radiation and liver procedures—for liver cancer patients who cannot have surgery. It may help shrink tumors while protecting liver function by using planned, targeted treatment.
Durham, North CarolinaAges 18 years+ - NCT07417605Recruiting
Using a new PET scan to tell cancer from inflammation after radiation
This study uses a special PET scan to tell the difference between leftover cancer and inflammation caused by radiation in people treated for head and neck cancer. It may help doctors know if more treatment is needed.
BrestAges 18 years+ - NCT03912519Enrolling by invitation
Testing two ways to numb lumbar back pain with radiofrequency
This study compares two needle-based techniques to treat long-lasting low back pain by stopping overactive pain signals from specific back joints. If you’ve already tried physical therapy and pain medicines without enough relief, this trial may test which technique works better for pain reduction.
Nashville, TennesseeAges 40 years+ - NCT04945148RecruitingPhase 2
Metformin plus radiation and chemo for glioblastoma subtype
This Phase 2 study tests whether adding metformin to standard radiation and temozolomide (chemo) can improve outcomes for people with newly diagnosed glioblastoma of a specific metabolic subtype. It aims to see if this combination is safer and more effective than standard treatment alone.
Suresnes, Hauts de SeineAges 18 years+ - NCT04959474Recruiting
Pre-surgery radiation study with or without calorie restriction
This trial looks at whether a planned calorie-reduction diet before surgery can change how early breast cancer responds to a short course of radiation. It may help people understand if diet could improve outcomes alongside standard pre-surgery treatment.
Philadelphia, PennsylvaniaAges 40 years+ - NCT04967976Recruiting
Breast mesh in two-step breast reconstruction after cancer
This trial studies whether using a supportive “mesh” during a two-stage breast reconstruction surgery is safe and effective for people rebuilding their breast after breast cancer. You might be a candidate if you have no signs of spread to distant organs and meet several health and body-size criteria.
Houston, TexasAges 18–70 - NCT04994067Recruiting
Registering radiation given during breast-conserving surgery
This study records details about radiation delivered while your surgery is happening for certain early breast cancers or pre-cancers. It may help doctors better understand who benefits most from this “intra-operative” radiation approach.
The Bronx, New YorkAges 18 years+ - NCT05002751Recruiting
Measuring how radiation affects vaginal narrowing in cervical cancer
This study measures how radiation therapy changes the vagina’s flexibility and shape in people with newly diagnosed, advanced cervical cancer that has spread to nearby lymph nodes. The goal is to better understand what happens over time, which may help guide prevention and treatment of vaginal narrowing.
La Jolla, CaliforniaAges 18–99 - NCT05009992RecruitingPhase 2
Drug combination for diffuse midline gliomas in children and young adults
This Phase 2 trial studies whether a combination of medicines (including ONC201/related study drugs) can better treat diffuse midline gliomas, a type of brain/spinal cord tumor that often affects the midline. You may qualify if your tumor diagnosis is confirmed and your treatment timing (before radiation, after radiation, or at recurrence) matches one of the study groups.
Birmingham, AlabamaAges 2–39 - NCT05010031RecruitingPhase 2
Lower-dose radiation for metastatic cancer with an ATM mutation
This trial tests whether giving a lower dose of radiation can help control metastatic tumors that carry a specific genetic change in the ATM gene. It may reduce side effects by using less radiation, while still aiming to keep the tumor under control.
Basking Ridge, New JerseyAges 18 years+ - NCT05011045Recruiting
Brain radiation study tracking thinking and memory changes
